Hardware Random Number Generator Core infrastructure.
|
|
|
|
To compile this driver as a module, choose M here: the
|
|
module will be called rng-core. This provides a device
|
|
that's usually called /dev/hw_random, and which exposes one
|
|
of possibly several hardware random number generators.
|
|
|
|
These hardware random number generators do not feed directly
|
|
into the kernel's random number generator. That is usually
|
|
handled by the "rngd" daemon. Documentation/hw_random.txt
|
|
has more information.

config UML_RANDOM

depends on UML
|
|
tristate "Hardware random number generator"
|
|
help
|
|
This option enables UML's "hardware" random number generator. It
|
|
attaches itself to the host's /dev/random, supplying as much entropy
|
|
as the host has, rather than the small amount the UML gets from its
|
|
own drivers. It registers itself as a standard hardware random number
|
|
generator, major 10, minor 183, and the canonical device name is
|
|
/dev/hwrng.
|
|
The way to make use of this is to install the rng-tools package
|
|
(check your distro, or download from
|
|
http://sourceforge.net/projects/gkernel/). rngd periodically reads
|
|
/dev/hwrng and injects the entropy into /dev/random.
